Eliminating AC/DC Wall Adapters for Low-Power Devices Using the Acroname USBHub3c The need for more efficient, space-saving, and simplified power solutions is rising in today's increasingly connected world. Many devices, especially in the industrial, medical, and consumer electronics markets, rely…

I. INTRODUCTIONThis case study demonstrates how a device lab resolved its USB issues using Acroname’s industrial USB hubs, making the lab more robust and ready to accommodate future expansion.Hardware device labs need reliable equipment. Often, these labs develop in an ad hoc manner, adding…

IntroductionMobile devices are built to maximize how long they can run between charges by topping off the battery when connected to power.  However, in mobile device and Continuous Integration (CI) labs, where hundreds of devices need continuous USB data connections, this presents a challenge…

I. Introduction to USB Power Delivery (PD) Sink TestingUSB Power Delivery (USB PD) is a convenient way to power a variety of devices.  Since a USB PD sink device could be connected to any PD source, sinks need to work safely and correctly with any source they might encounter.The USBHub3c by…

Replication of testing environments is a known challenge in the Functional Circuit Test world. Wiring an FCT fixture using wire wrap can take hours, and the validation of a tester itself, to ensure simple continuity and function, can take days. Anyone setting up a fixture-based test bench or rack-…

Create and Deploy Wireless Test FixturesOne of the benefits of using Acroname's BrainStem/MTM series modules in functional circuit test is being able to create and deploy "wireless" test fixtures - a fixture with no wire-wraps or cables. The small form-factor and low power of MTM modules can be…

Two example projects for USBHub2x4 With National Instruments We've recently been getting questions regarding the use of the Acroname USBHub2x4 from within National Instruments TestStand test management software. So we put together two example projects which wraps the BrainStem2 library…

Connecting multiple USB hubsIn this week's video we answered the popular question of: "Can I connect more than one USBHub2x4/BrainStem device to my computer?".  Not only did we prove that the answer is yes, but we also wanted to see exactly how many devices we could connect using our…

Not only do we make Manufacturing Test Modules (MTM), we also use them to test our own products. Using BrainStem® MTM modules to make a functional board level test system is incredibly simple. For the USBHub2x4, MTM allows us to make a test system that requires no external test equipment…

Using BrainStem Python for Turning USB Device On And Off Simple task automation for repetitive actions can be powerful aids in product development. Automatically connecting and disconnect devices from a USB bus is commonly done in manufacturing test and software regression test systems.…
